SPECIFICATION forming part of Letters Patent No. 742,240, dated October 27, 1903.

I Application filed January 17. 1903. Serial No. 139.418. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM E. SEANOR, a

citizen of the United States, and a resident.

of Hope, in the county of Kootenai and State of Idaho, have invented a new and Improved Wrench,of which the following is a full, clear,

and exact description. I

The purpose of the invention is to provide a wrench in which the movable jaw can be expeditiously and conveniently adjusted upon the shank or body of the Wrench to and from the fixed jaw and as conveniently and rapidly locked in adjusted position against all strain to which the movable jaw may be subjected, and to accomplish the foregoing results with a construction which is simple, economic, and reliable.

The invention consistsin the novel conaw, actuating-nut, and locking device, the

said view being drawn on an enlarged scale.

Fig. 3 is a transverse section taken practically on the line 3 3 of Fig. 2. Fig. 4 is a vertical section taken substantially on the line 44 of Fig. 3. Fig. 5 is a fragmentary exterior view of the threaded portion of the body-shank of the wrench; and Fig. 6 is a sectional side elevation of themovable jaw and a side elevation of a portion of the shank upon which the movable jaw slides, illustrating a slight modification in construction.

A represents the shank or body of the wrench, which is provided at its front and rear edges with threads 10, and these threads are made tapering or are brought to a point, as is shown at 11 in Fig. 5, in order to engage more readily with the threads in the nut 14, hereinafter described. The fixed jaw O is attached to the shank A in the customary manner.

The lower or movable jaw B is provided with a guidey0ke consisting of a guard-standard 12, which extends down from the under s side of the lipsection of the said jaw B, and a ring-section 13, integral with or attached to the said guard-section 12. The guard-section 12 is located in front of the body-shank A, and the ring-section 13 loosely receives the said shank.

- ment with the'threads of the body-shank A or are opposite the side faces of the said bodyshank, the nut 14, and consequently the lower or movable jaw B, may be freely moved to and from the fixed jaw C, so as to make a quick adjustment relative to a nut or other object to be clamped or operated by the wrench.

The nut 14 is provided with an exterior annular groove 16 and with recesses 17 and 18 in the back wall of the groove. These recess es are diametrically opposite, and are produced in the outer surface of the nut at the back of the threads 15 and 16, as is also shown in Fig. 3. In connection with the nut 14 a locking-spring 19 is employed, which is in the form of an open ring loosely fitting in the groove 16 in the exterior of the said nut, and the said locking-spring has a depressed section 20, which when it entersa recess 17 or 18 serves to hold the nut 14. stationary, and consequently the lower or movable jaw B in its adjusted position. a

The ends 21 of the spring 19 are more or less dovetailed in cross-section and are made to enter, preferably, dovetailed recesses 22 in fitting the terminals of the said lockingspring in the recesses 22 or by securing them therein through the medium of a screw, a pin, or the like, or, if desired, one terminal member 21 of the locking-spring 19 may have movement in its recess 22.

Instead of a locking-spring 19 being employed to hold the adjusting-nut 14L in its adjusted position a ever may be utilized instead, as is illustrated in Fig. 6, in which figure it will be observed that the adjusting-nut It is provided with opposing recesses 23 and 23, exteriorly located and more pronounced than the depressions l7 and 18, (shown in Fig. 3,) and the guide-section 12 of the yoke carried by the lower or adjustable jaw B is provided with a longitudinal chamber 24, in which chamber a lever is fulcrumed between its ends by a suitable pivot-pin 26, and this lever is provided at its upper end with a head 27, adapted to enter either of the reeesses 23 and 23, the head 27 being normally held in position to enter the said recesses by a suitable spring 28. Under this latter construction when the nut is to be released from the looking-lever 25 the lower end of the lever is carried inward, as is shown by dotted lines in Fig. 6, thus removing its head 27 from the recess 23 or 23, which it may have entered, thus permitting the nut let to be freely turned, whereas when thelocking-spring 19 is employed to hold the adjusting-nut of the wrench in looking position i the nut may be carried from looking engagement withthe spring by forcibly turning the nut by the fingers against the resistance of the spring.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a wrench the combination with a threaded shank having a fixed jaw and a movable jaw cooperating therewith, of a nut carried by the movable jaw and having threaded engagement with the shank and adapted to rotate thereon to operate said movable jaw, said nut having an annular recess with depressions in its back wall, and a spring carried by the movable jaw and having a section adapted to engage one of said upon the body-shank and provided with a.

yoke extending in direction of the inner end of the said body-shank, a not held to turn in the said yoke, freely around the body-shank, the said nut being provided with interior diametrically opposite broken threads, the adjusting-nut being also provided with a plurality of recesses on its outer periphery, and

' a locking device carried by the yoke and held to yieldingly engage one or the other of said recesses for the purpose described.

3. In a wrench, the combination with a shank having opposing flat sides and threads at its front and rear edges, and a jaw fixed to the outer end of said shank, of a second jaw movable on the body-shank to and from the fixed jaw, a yoke carried by the movable jaw andloosely received by the said bodyshank, a nut carried by the said yoke,which nut surrounds the body shank and is provided with interior diametrically opposite broken threads and with exterior diametrically opposite recesses, and an open lockingring having its ends attached to the said yoke and its body portion fitted around the exterior of the said adjusting-nut, the said locking-ring being provided with a depression adapted in one position of the adjusting-nut to enter an exterior recess therein, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
